FOUNTAIN-PEN.

Totali whom it may concern.'

Be it known that I, HARRY XV. lVooD, a citizen of the United States, residing at Col.- fax, in the county of Jasper and State of Iowa, have invented va certain new and useful Fountain-Pen, of which the following is a specification.

My invention relates to that class of fountain pens in which the ink reservoir comprises a flexible tube which is compressed to exclude thevair and is permitted to expand and draw in asupply of ink.

It is my object t0 provide in such a pen convenient means whereby the flexible ink reservoir may be quickly and easily compressed by the operator.

More particularly, it is my object to pro-v vide a cover plate g and connected parts whereby such an ink reservoir may be coinprcsscd, which cap when not in use to compress the ink reservoir will lie close to the body of the pen and may be locked in position to form part of the outer cylinder of the pen so that it will not readily become accidentally loosened and to prevent accidental compression of the ink reservoir.

A further object is to provide a self filling fountain pen having a compressor bar made from a single piece of metal, a rover plate and a spring on the compressor bar adapted to hold the cover plate in position when the pen is closed and designed to hold the cover plate in vertical position when it is used to depress the compressor bar.

A further object is to provide such a device constructed of few and similar parts which may be easily and vinexpensively manufactured and assembled and which will not easily wear out.

My invention consists in certain details in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which- Figure 1 shows a central, longitudinal, sectional view of a portion of a fountain pen embodying my invention showing the 1 cover plate in its closed position. The dotted lines show the position of the cover plate after the first operation in filling the pen. The view is taken on the line l-l of Fig, 6. lig. 2 shows a perspective view of the cover plate. Fig. 3 shows a central vertical, longitudinal, sectional view of the pen holder Specification of Letters Patent.

cylinder', with the parts in position for compressing the flexible ink reservoir. Fig. 4 shows an enlarged, detail plan view of the compressor plate with the spring thereon. Fig. shows a topor plan view of a portion. of the pen cylinder showing the slot therein. Fig. 6 shows a central, transverse vertical sectional View through a Jfountain pen embodying my invention taken on the line 6-6 of Fig. 1.

My pen comprises an ordinary cylinderror barrel 10, provided with an ordinary screw threaded portion not shown, for holding the pen point. lVithin the cylinder 10 is a flexible inlrreservoir l2. Between the ink reservoir and the cylinder 10 is a compressor plate 13 for compressing the ink reservoir 12. The .compressor plate 13 extends longitudinally within the cylinder as shown in Fig. 3, and is preferably cut from a single piece having slde wings 14 opposite each other and side wings 15 opposite each other and spaced apart from the side wings 14. The portions of the side wings in the blank,

are shown by the ddtted lines in Fig. 4.'

The side wings 1-l are provided with extensions 1G which in the blank are parallel with the compressor plate as shown by the dotted lines in said Fig. 3. ln completing the compressor' plate the side wings 1l are bent at right angles to the plate 13 and the extensions 16 are bent. inwardly toward cach other at right angles to said side wings 111-. The side wings l5 are bent at right angles to the bar 1?).

For convenience of description, I will call the end of the pen which holds the point, thc lower end and the other end, the upper end.

spring 17 'is mounted on the compressor plate 13 in the following manner: ln the upper surface of the ron'lpiessor plate lf, is a depression or recess 19) which extends from a point spaced apart from the side wings l-/t on the side toward the lower end of the pen to a. 4point between the side wings l5. The depression lf3 is angula r in outlineand at its upper end is an. extension lil lnarmovement. On the lower surface of the spring 17 are lugs 17b which hold the springy 17 spaced apart from the bottom of the de-l pression or recess 13. On the upper surface,V

of the spring 17 between the lugs 17 b is a lug 100 the purpose of which will be hereinafter explained. The end of the spring 17, nearest the upperv end of the pen, is narrower than the main body thereof so that it may is a slot 23, 'the shape of which will be hereafter described. The purpose of the slot 23 i lower end of the pen.

is to permit the admission to the interior of the cylinder of the cover plate wherebyl the compressor plate may be operated to compress the ink reservoir. For covering the slot 23 I have provided a cover plate 24 of suliicient length to cover the slot.23. The cover plate 24 is provided with a central, longitudinal, downwardly extending portion 25 extending from the lower end approximatelylhalf the length of said cover plate.4 The portion 25 may be made integral with the cover plate as shown in Fig. 6, or may be secured thereto as shown in Fig. 2. On each side of the portion 25 adjacent to the body portion of the cover plate 24 are longitudinal slots 26 in which are received the ends of the extensions 16 as shown in Fig. 6. The slots 26 extend to a point near the end of the cover plate 24 adjacent to the See Figs. 1 and 3. The upper end 27 of the downward extending portion 25 is preferably made entirely separate from the cover plate 24 and is dovetailed tothe rest of the portion 25 and detachably secured thereto by means of a pin 28, as shown in Figs. 2 and 7. The end 27 is made detachable for convenience in` assembling the parts of the pen.

In the lower surface of the portion 25 in the end thereof, adjacent to the upper end of the pen is a transverse recess 27 designed to receive the lug 100 when the cover plate is in its closed position and to lock said plate in such position, as shown in Fig. l. In the other end of the portion 25 adjacent to the main body'of the cover plate 24 is a notch 24 designed to receive the edge of the cylindcr 1() when the cover plate is in closed position as clearly shown in Fig. 1, and also to receive the lug r 100 on the spring 17, when -the cover plate is in position for filling as shown in Fig. I. The slot 23 is :formed as follows: It is substantially rectangular and slightly shorter and narrower in length than the cover plate 24. .\t. its upper end, the slot 23 is formed with lateral extensions 32 of proper size and properly located to receive the side wings 15 when the pen is filled and the compressor plate is raised. Between the middle of the slot 23 and the .lower end thereofg said slot is constructed with lateral extensions 31- of proper form and properly located to receive the cover plate 124 when the cover is raised to position at right angles The slot 23 is also provided with lateral extensions 33 to receive vthe wings, 14 when the compressor plate 4is raised.

In the practical use of my improved foun the cylinder 10 as shown in Fig. 1, over the slot 23. The ycompressor plate 13 restsladcylinder, assuming that the slot in saidxcylinder' is upward. The lug 100 -is received in its closed positidn. The raised4 end "ofthe spring 17 extends into the space between the compressor plate 13 and the upper end of the cover plate.

reservoir, und to fill the pen the cover late 24 is pushed toward the upper en d o the pen cylinder. The extensions 16 slide freely in the slots 26. As soon as the end of the portion 25 adjacent to the lower end of the pen has moved toward the upper end of the pen far enough to engage the extensions 16, the raised end ofthe spring engages the other end of the portion 25 and raises the cover 1. The cover plate 24 may then be easily elevated to vert-ical position when the lug location of thelugs 17b and of the lug 100 is such as to hold the cent-ral part of the spring spaced apart from the bottom of the and enables me to utilize its full resiliency for locking the cover plate in its closed posiwhen the lug 100 is received in the recess 24. In the lower and of the cover plate 24 is ing the cover plate to be moved to position .at right angles to the compressor bar'13 without engaglng the spring 17. A similar plate for the purposes of s mmetry.

To close the pen after tlie reservoir .12 is filled, the cover plate is raised verticall and then lowered to position parallel wit the surface of the cylinder 10 and shovedtoof the cylinder enters the notch 24u and the cover late wholly covers the slot 13 as shown 1n Fig. 1, and by the dotted lines in Fig. 5.

A considerable numberof variations in to the longitudinal axis of thepen and in-' serted into the cylinder as shown in Fig. 3.,

tain pen, the. cover plate normally -restsjon jacent to the upper, inner surface of the 100 will enter the recess 24a and the cover platemay be inserted into the cylinder 10 through the slot 23 as shown in Fig. 3. The

a notch 30 whichis for the purpose of allow-Y ward the lower end ofthe pen until the edge'v the-recess 27 thus locking the cover plate '4 l/Vh'en it is desired to compress the ink leo recess 13". This permits considerable movei ment of the central portion of the spring. 17 l tion and for holding the cover plate upright notch is cut in the other end of the coverl the construction of my improved fountain pen may be made without departing from the essential spirit of my invention.

My fountain pen has many advantages, particularlyin the construction of the compressor plate 13 and the spring 17 and also of the cover plate 24 and in the cheapness with which these parts may be constructed. My compressor plate 3 is made of a single piece of metal and is completed with few and simple operations. The spring 17 can be made at a minimum of expense. The

lug 100 locks the cover plate in its closed position. The raised end of the spring 17 slightly raises the upper end of the cover plate when the latter is moved longitudinally toward the upper end of the pen mak- -mg 1t easy to raise the cover plate when it 1s desired to insert it into the pen cylinder for the purpose of compressing the ink reservoir 12.

I claim as my invention: 1. In a device of the class described, a compressor plate having side wings bent at 'right angles to said plate, opposite eXtensions on the free ends `of side Wings adjacent to each other at right angles to the free ends of said side wings, a cover plate pivotally and slidably mounted on said extensions, a sprin on said compressor plate having a lug esigned to engage said cover plate to hold the latterfin its closed position, said cover plate being provided with a transverse recess on its lower surface designed to receivel said lug when the cover plate is ing a slot in one side thereof, a compressor plate therein having a recess in its upper surface, a cover plate designed to cover said slot, pivotally and slidably mounted on said compressor plate, a recess in the lower side of said cover plate, a spring received in the recess in said compressor plate, a lug on said spring designed to be received in said recess in said cover plate when the cover plate is closed and to lock same in its closed position.

In a fountain pen, a pen cylinder having a. slot in one side thereof, a compressor plate therein having a recess in its upper surface, av cover plate pivotally and slidably mounted on said compressor plate and designed in 011e position of its movement to cover said slot, a spring received in the recess in said compressor plate having a portion inclined toward sald cover plate and designed to engage said cover plate and raise one end of same when said cover plate is moved longitudinally from its closed position, downwardly extending lugs on said spring designed to hold it spaced apart from the bottom of said recess.
